Question

k. a student graphs the motion of a toy car. the student graphs the data from their investigation. which two statements describe the graph? circle your answer. motion of toy car a. the average speed of the toy car in this investigation is 3.33 m/s. b. the average speed of the toy car in this investigation is 0.3 m/s. c. the toy car decreases speed throughout the investigation. d. the toy car remains at a constant speed throughout the investigation. e. the toy car increases speed throughout the investigation. l. what is the average speed of the toy car? 0.5 m/s

Explanation:

Step1: Recall average - speed formula

The formula for average speed is $v = \frac{d}{t}$, where $d$ is the total distance traveled and $t$ is the total time taken.

Step2: Identify values from the graph

From the graph, the total distance $d = 15$ m and the total time $t=50$ s.

Step3: Calculate average speed

$v=\frac{15}{50}=0.3$ m/s. Also, the slope of the distance - time graph is increasing, which means the speed is increasing.

Answer:

B. The average speed of the toy car in this investigation is 0.3 m/s.
E. The toy car increases speed throughout the investigation.
